CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 512,194, dated January 2, 1894.

Application filed June 6,1893- Serial No- '7 ,7 No model.

T0 015 whom it may concern.-

Be it known that I, DANIEL HUNT, a citizen of the United States, residing at Round Grove, in the State of Missouri, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specification.

My invention relates to car couplings of that character or description in which the cars are automatically coupled when they come together, thus obviating the necessity of a brakeman or other party going between the cars in order to couple them.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a plan view of a car coupler constructed in accordance with my invention. Fig. 2 is a front view of one of the couplers. Fig. 3 is a plan view on an enlarged scale, of one of the draw bars detached.

As each coupler on the end of a car, is identical with or a counterpart of the other with which it engages, a description of one thereof will be sufficientto enable my invention to be fully understood.

In the said drawings, the reference letter A, designates the horizontal beams and A the cross beams of an ordinary car platform, while the letter B,designates a cross plate at each end of the car, secured to the upper sides of said horizontal beams.

The letter A denotes the draw bar having its outer end formed with a hook A beveled as shown in Fig. 3, and with a notch A On its opposite side the draw bar is formed with a projecting lug D. At its inner end the draw bar is formed with a shank or stem F, the ends of which are cut away leaving an intermediate enlarged portion F. This stem has its bearings in the cross beams A A and between said cross bars and the enlarged portion F are interposed coiled springs G. The apertures in the bars or beams A through which the stem F passes are enlarged,

so that the draw bar is capable of a lateral or sidewise movement. Secured to the outer beam A is a spring E, the free end of which bears against the draw bar, and the tendency of which is to force said draw bar laterally inward or toward the center of the car. There is a similar spring E, secured to cross bar B, the free end of which is adapted to strike the end of the draw bar of an approaching car.

Pivoted to a cross bar 11, secured to the horizontal beams A is a two-arrned lever I, the short arm K of which is adapted to engage with the notch A in the draw head and force the latter outwardly when the other end of said lever is raised.

The letter L designates pins passing through apertures in bar B and through aligned aper tures in bottom cross bar B. These pins serve as stops to limit theoutward movement of the draw heads. The lugs D serve as bumpers when the cars approach each other.

Having thus described my invention, what I claim is- 1. In a car coupling the combination with the draw head, having a beveled hooked end and a notch in its side, of the stem having its ends reduced forming an intermediate enlarged portion, and having its bearings in enlarged apertures in the cross bars of the car platform, the coiled springs and the two DANIEL HUNT.
